Jose, a few more thoughts: 1. You have changed a Datum Plane name to deal with what I have called the "Z-up" problem over the years. The Pro/E convention, for perfectly good "CAD reasons" (relative to X-Y sketches in the plane of the screen), is that Z comes out of the screen. This conflicts of course, especially for those of us who are going to take parts into Pro/NC, with TOP being the Y-zero plane. In addition to TOP being Z-zero instead, I have found it desireable that I look at the model with Z up on the screen. This can be dealt with in a few ways: (1)Use a custom CSYS instead of Default, (2)Use the config options x_angle, y_angle, and orientation user_default, (3)Redefine the Default Orientation (as opposed to the Standard Orientation), or (4)Define your own rotated view and call it Z-UP or something similar. BTW, I like to have reduced name clutter so I use the names X,Y,Z or X0,Y0,Z0 for my planes and 0 or 000 for my CSYS. 2. You asked about other things to include in a Start Part. (a) My Start Part has a Mass_Prop Analysis Feature followed by a CSYS placed at the COG using Relations. You have to Regenerate twice to make it update after changes. (b)You can also create a parameter WEIGHT and access the Analysis Feature to have it automatically calculated, as well. (c)If you include WIDTH, HEIGHT, and DEPTH (or X,Y,Z) as required parameters to be filled out when you start, you can change that default block at the outset without having to Edit it. (4)Other commonly included parametes include PART_NO, REVISION, & MATERIAL. David
